How to solve LR game problems ? Please provide an easy way...

Hi Jeet,
There is no one easy way to solve these kind of problems. Only thing you can use to solve these questions is logic. What I would recommend is to solve as many different types of such questions as possible. When it comes to games and tournaments, tabulating the data helps a lot. So a general approach would be as follows:
1) Write down the information in a table format
2) If there is missing or incomplete data, make different versions of the table. Usually, all alternate versions except the correct one will prove to be infeasible as we try to fit in the remaining data
3) If the game is a knockout, draw a tree structure with converging branches

Hope this helps. There are a couple of good sources to prepare for these types of questions. Find them below:

First try to understand the given data (Type of tournament, number of matches possible, elimination rules if any, ) Tabulating the data helps you. Read the blog on how to solve Games and Tournaments for CAT. It will help you solve these type of questions
